COMBINED CORN AND COTTON PLANTER.

Specification of Letters Patent.

Patented Aug. 2, 1910.

Application filed July 25, 1908. Serial No. 445,348.

To oll whom it may concern:

Be it known that I, WVILLIAM S. GRAHAM, a citizen of the United States,residing at Canton, in the county of Fulton, State of Illinois, haveinvented certain new and useful Improvements in Combined Corn and CottonPlanters, of which the following is a specification, reference being hadto the accompanying drawings.

My invention relates to corn and cotton planters, and has for its objectto provide a new and improved construction of machine which shallperform the functions heretofore performed by separate machines forplanting corn and cotton seeds.

It is desirable in many instances to plant the cotton seed closertogether than the corn, and it is the principal object of my inventionto provide new and improved means in one machine for planting atdifferent distances apart. I accomplish this object by the meansillustrated in the drawing and hereinafter specifically described.

That which I believe to be new will be set forth in the claims.-

I The figure is a top or plan view of my improved machine, with one ofthe hoppers removed.

In the drawing, 10 indicates the main frame of the machine, journaled onaxle 11, provided with carrying wheels 12, which are non-rotatablyconnected with said axle by means of pins passing through the hubs ofthe wheels and through the axle. As shown, the axle 11 extends somelittle distance beyond the frame 10 at each side of the machine, and isprovided with a plurality of holes through which the retaining pins maybe passed in order to hold said .wheels in place at any of a pluralityof positions. It will be evident that the wheels may be reversed,bringing the short ends of the hubs next to the frame so as to enablethe wheels proper to be placed close beside the frame. The frame 10 ispivotally connected at its forward end to bars or brackets 13 which arebolted or otherwise secured between the cross-bars 14 of therunner-frame of the planter.

15 indicates runners or furrow-openers of the ordinary type, and 16 theordinary runner-shanks or conductors mounted on the front-frame of theplanter.

17 indicates the hand-lever by which the runners are adapted to be movedup and down, in the usual manner, the hand-lever mechanism beingprovided with steps 18 and 20 on opposite sides of the pivotal point ofsaid lever by means of which the manipulation of the lever 17 and theadjustment of the runners are rendered easy.

21 indicates a seat suitably supported from the main frame 10.

22 indicates a divided shaft journaled in the brackets 13 of thefront-frame of the planter. The two end portions of this shaft- 22project into a sleeve 23 to which they are connected by means of cotterpins 2%, a plurality of holes being provided through said sleeve forsuch connection.

25 indicates a sprocket-wheel keyed or otherwise non-rotatably securedon the sleeve 23.

2627 indicate different-sized sprocketwheels mounted on the axle 11 soas to rotate therewith.

28 indicates a sprocket-chain connecting the sprocket-wheel 25 witheither sprocketwheel 26 or 27.

29 indicates bevel-gears one of which is keyed or otherwise suitablysecured near the outside end of each portion 22 of the divided shaft.

30 indicates one of the seed-hoppers, the seed-dropping mechanism ofwhich is operated by the gear 29. Inasmuch as it is desirable to plantcotton seed closer than corn, in general, as set forth above, and as itis sometimes desirable to plant either at varying distances apart,provision is made for shifting the seed-boxes 30 and the operatingmechanism connected therewith laterally of the machine. hen such a shiftis made, it will be understood of course that, through the medium of thedivided shaft 22 and the plurality of holes in which the cotter pins 24:may be inserted, the end portions 22 of the divided shaft and the bevelgears 29 may be shifted laterally to correspond with the position of theseed-boxes, the latter being shifted, together with their connectedparts, in any approved manner.

For the purpose of covering the seed, I provide shovels 33 carried bystandards 34 which are adjustably secured by means of corrugated bearingplates 35-36 upon shovel-frames 31 suitably secured at their front endsupon the front frame of the planter.

Check-rower mechanism of the ordinary type is provided, the check-rowerhead being indicated by 60, the forks by 61, and the usual transverserock-shaft by 62, the connections between the fork 61 and the rockshaft62 being by means of arms 63 and links 64:, so that the rock-shaft isgiven a partial rotation at each throw of the fork, suitable valvemechanism being provided in the shank or conductor adapted to be openedat each throw of the fork 62, as will be readily understood.

69 indicates a bracket non-rotatably mounted on the rock-shaft 62,having an upward and a downward extension. To the downward extension isattached one end of a spring 70 whose other end is suitably secured tothe front-frame forward of said bracket. This spring serves to returnthe rock-shaft 62 to normal position after each throw of the check-rowermechanism. Pivotally attached to the upward extension of said bracket 69is a link 71 which is also pivotally connected to a pivoted foot-lever 72, by means of which the operator can turn the rock-shaft 62 at the endsof the rows after the check-rower mechanism has ceased to operate inorder to properly space the hills at that point, as will be readilyunderstood.

If the planter is to be used as a drill, the spring 70 is merely to bedisconnected from the downward extension of the bracket 69 and hookedover the pin 73 on the upward extension of said bracket. This springthen causes the rock-shaft to remain in its turned position, holding thevalve in the shank constantly open, and permitting the seed to fall intothe furrow as rapidly as it is discharged from the seed-hoppers, the arm63 slipping forward along the link so as not to move out of normalposition the forks 61 of the checkrower mechanism, as will be readilyunderstood.

What I claim as my invention and desire to secure by Letters Patent is,

1. In a combined corn and cotton planter, the combination with a frontframe, a bracket mounted on said front frame at each side thereof, arear frame pivotally mounted on said brackets, an axle carried by said.rear frame, and carrying wheels fixed on said axle, of a sleeve bearingat its ends against said brackets, a divided seed-shaft each part ofwhich is adapted to be secured to said sleeve at various positions ofadjustment, and means for driving said sleeve from said axle.

2. In a combined corn and cotton planter, the combination with a frontframe, a bracket mounted on said front frame at each side thereof, arear frame pivotally connected to said brackets, an axle carried by saidrear frame, and carrying wheels fixed on said axle, of a sleeve bearingat its ends against said brackets, a divided seed-shaft each part ofwhich is journaled in one of said brackets and extends into and issecured to said sleeve at any desired position of adjustment therein,and means for driving said sleeve from said axle.

3. In a combined corn and cotton planter, the combination with a frontframe, a bracket mounted on said front frame at each side thereof, arear frame pivotally connected to said brackets, an axle carried by saidrear frame, and carrying wheels fixed on said axle, of a sleeve bearingat its ends against said brackets, a divided seed-shaft each part ofwhich is journaled in one of said brackets and ext-ends into and issecured to said sleeve at any desired position of adjustment therein, asprocket wheel fixed on said sleeve, a sprocket-wheel fixed on said axlein alinement therewith, and a sprocketchain connecting said two sprocketwheels.

4. In a combined corn and cotton planter, the combination of a frame, anaxle carried by said frame, axle, a sleeve, a divided seed-shaft eachpart of which extends into and is secured to one end of said sleeve atany desired position of adjustment therein, a sprocket wheel fixed onsaid sleeve, a sprocket-wheel fixed on said axle in alinement therewith,a sprocketchain connecting said two sprocket-wheels, and means adjacentto the ends of said sleeve for revolubly supporting the parts of saidseed-shaft and adapted to hold said sleeve against movement transverselyof said frame.
